hot removal of un-used netapp shelves

we added 2 shelves to existing loop and totally forgot that number of drives supported / loop is 24 * 10 = 240 only . Now there are 11 shelves in a loop. What are the option of hot removing the newly added shelves which are not used yet Can we remove the cables one at a time and go back to original last shelf and then connect the new shelves to different SAS ports and create a new loop.
